Paul Mackerras 35499c0195 powerpc: Merge in 64-bit powermac support.
This brings in a lot of changes from arch/ppc64/kernel/pmac_*.c to
arch/powerpc/platforms/powermac/*.c and makes various minor tweaks
elsewhere.  On the powermac we now initialize ppc_md by copying
the whole pmac_md structure into it, which required some changes in
the ordering of initializations of individual fields of it.

Paul Mackerras 5d14a18d59 powerpc: Fix some bugs in the new merged time code
I had the sense of the test for when to use the old 601-style RTC
registers inverted.  pmac_calibrate_decr and via_calibrate_decr
weren't setting ppc_tb_freq, on which all the further calculations
depended.  Lastly, update_gtod was losing the top 32 bits of
the new tb_to_xs value.

Paul Mackerras f2783c1500 powerpc: Merge time.c and asm/time.h.
We now use the merged time.c for both 32-bit and 64-bit compilation
with ARCH=powerpc, and for ARCH=ppc64, but not for ARCH=ppc32.
This removes setup_default_decr (folds its function into time_init)
and moves wakeup_decrementer into time.c.  This also makes an
asm-powerpc/rtc.h.

Paul Mackerras 143a1dec7e powerpc: Merge machdep.h
A few things change for consistency between ppc32 and ppc64:
idle functions return void; *_get_boot_time functions return
unsigned long (i.e. time_t) rather than filling in a struct rtc_time
(since that's useful to the callers and easier for pmac to
generate); *_get_rtc_time and *_set_rtc_time functions take
a struct rtc_time; irq_canonicalize is gone; nvram_sync returns
void.

from the *_message_pass() functions, and removes the call to the

Stephen Rothwell 3a5f8c5f78 powerpc: make iSeries boot again
On ARCH=ppc64 we were getting htab_hash_mask recalculated
to the correct value for our particular machine by accident.
In the merge tree, that code was commented out, so htab_hash_mask
was being corrupted.

We now set ppc64_pft_size instead which gets htab_has_mask
calculated correctly for us later.  We should put an
ibm,pft-size property in the device tree at some point.

Also set -mno-minimal-toc in some makefiles.
Allow iSeries to configure PROC_DEVICETREE.

Paul Mackerras fd582ec88e ppc: Various minor compile fixes
This fixes up a variety of minor problems in compiling with ARCH=ppc
arising from using the merged versions of various header files.
A lot of the changes are just adding #include <asm/machdep.h> to
files that use ppc_md or smp_ops_t.

This also arranges for us to use semaphore.c, vecemu.c, vector.S and
fpu.S from arch/powerpc/kernel when compiling with ARCH=ppc.

Paul Mackerras 9b6b563c0d powerpc: Merge in the ppc64 version of the prom code.
This brings in the ppc64 version of prom_init.c, prom.c and btext.c
and makes them work for ppc32.  This also brings in the new calling
convention, where the first entry to the kernel (with r5 != 0) goes
to the prom_init code, which then restarts from the beginning (with
r5 == 0) after it has done its stuff.

For now this also brings in the ppc32 version of setup.c.  It also
merges lmb.h.

This updates the powermac SMP code to use the mpic driver instead of
the openpic driver and fixes the SMP-dependent context switch code.
We had a subtle bug where we were using interrupt numbers 256-259 for

numbers 252-255 instead.

Paul Mackerras 14cf11af6c powerpc: Merge enough to start building in arch/powerpc.
This creates the directory structure under arch/powerpc and a bunch
of Kconfig files.  It does a first-cut merge of arch/powerpc/mm,
arch/powerpc/lib and arch/powerpc/platforms/powermac.  This is enough
to build a 32-bit powermac kernel with ARCH=powerpc.

For now we are getting some unmerged files from arch/ppc/kernel and
arch/ppc/syslib, or arch/ppc64/kernel.  This makes some minor changes
to files in those directories and files outside arch/powerpc.

The boot directory is still not merged.  That's going to be interesting.
